Two collocated AQY R air quality monitoring sensors were installed at a monitoring site in East Hartford, Connecticut to evaluate its performance tracking gas, particulate and meteorology data over a year long time frame. Hourly data for O3, NO2, PM2.5, PM10, temperature and relative humidity were compared to reference monitors located at the same site. The full downloadable dataset used is located here Download CSV.

MOMA calibration was used on NO2 data after May 30th 2024, this pre-calibrated data is separated from calibrated NO2 data for correlation comparisons.
